' NURSING-BOTTLE.

Specification of Letters Patent.

Patented Dec. 27, 1910.

Application filed August 30, 1909. Serial No. 515,161.

To all whom it may Camera:

- and applied nipple Be it known that I, ROBERT A. VnN CLEAVE, a citizen of the United States, res ding in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful N ursing-Bottle, of which the fol- I lowing is a specification.

My inventlon relates to the class of nursing bottles of the type having a passage or duct leading from the exterior of the bottle to the interior thereof to supply the bottle with air to allow of the ready withdrawal of the milk or fluid, to render suction more easy for the child and prevent collapsion of said nipple. In such bottles, it has been found di cult or impossible to construct the air passages or tubes owing to the fact that the heat necessarily employed informing the same injures the same and thus closes or clogs the bore thereof. 7

The present invention consists in applying to anursing bottle a tube individually separate from the bottle,

and in the mouth ortion for firmly securing the latter in position. For the tion, the accompanying drawing illustrates a satisfactory reduction of the same to practice, but the important instrumentalities thereof may be varied, and so it is to'be understood that the invention is not limited to the specific arrangement and organization shown and described.

Figure 1 represents a side elevation of a nursing bottle embodying my invention.

. Fig. 2 represents a longitudinal section from the bottle.

thereof on line m-w, Fig. 1. Fig. 3 represents'a transverse section on line y-y, Fig. 2. Fig. 4 represents a perspective view of a portion of the air passage or duct removed Fig. 5- represents a face new of a portion of a modification.

Similar numerals of reference indicate corresponding parts in "the figures:

' Referring to the "drawing:1' designates a nursing bottle, the same having a neck 2, mouth 3 and bead-4:,as usual in such cases, but as to the form of the-bottle, I do not limit myself.

On a side of thebody of the bottle is the tube 5, which is open from end to end and primarily individually separate from said and employing some of the material of the bottle at the slde thereof,

purpose of explaining the inveni body, it being seated in a groove 6 in said side and engaged by the walls thereof, whereb it islfirmly held in position, one end of sai tube communicating with the atmosphere, and the other end assing through the wall of the mouth 3 and terminating at said mouth soas to communicate with the interior of a nipple and consequently the bottle when-said nipple is applied to the'bottle. The bead 4 removes the terminal of the tube at the mouth ortion of the bottle from contact with the l fand While strengthening said portion, which otherwise is pierced for the passage therethrough of the adjacent portion of the tube and allowing also the bottle to be carried by said bead without liability of fracturing the portion of the tube in the latter, the bead also affording more room for the occupation of the portion of the tube therein. The walls of the groove 6. form lips 7'Wl1lCh when in molten or soft condition are turned or worked over the tube so as to embrace the same and so rigidly connect it with the bottle, while the tube is guarded from contact and consequent fracture.

In Fig. 5, I show the bottle having the of the shape of the bottle desired and blow the bottle, when some of the molten glass flows around the tube'and embeds or partially embeds the same in the oove 6, created in the bottle in the formatlon of the latter at the place of occupation of the inserted tube. Inall cases, the tube has its bore preserved intact from end to end and so is not closed or clogged, as is thecase where a passage is molded on the bod the same being affected and injured by the heat required in. blowing the" bottle with such passage in (position and so is stroyed an feet is remedied by the use and employing the material of the latter as the means for securing the. tube in position.

practically derendered worthless, whicli'deof a tube indi-'. vidually'separate and distinct-from the body This leaves the tube intact throughout with-' out having its bore reduced or destroyed, and

.a wire or other suitable-implement may be passed or drawn through the same so as to thoroughly clean the bore.

- Having thus described my invention, what I claim as new and desire to secure by Let- 5 ters Patent, is

1. A nursing bottle, open at' both ends and secure by being partly embedded and fused in the outside of the body of the bottle and wholly embedded and fused in and. through-the bead at the bottle mouth.

2. A nursing bottle, and a se arate tube op'en'at both ends" and secure by being partly embedded and fused in and ion i- 15 tudinally to the outsideof the bottle b0 y and a se arate tube and wholly embedded and fused in and throuih the bead at the bottle neck.
